Heteromita
Cercomonads are small flagellates, widespread in aqueous habitats and common in soils. Characteristics The cells are generally around 10 μm in length, without any shell or covering. They produce filose pseudopods to capture bacteria, but do not use them for locomotion, which usually takes place by gliding along surfaces. Most members have two flagella, one directed forward and one trailing under the cell, inserted at right angles near its anterior. The nucleus is connected to the flagellar bases and accompanied by a characteristic paranuclear body. Classification Genetic studies place the cercomonads among the Cercozoa, a diverse group of amoeboid and flagellate protozoans. They are divided into two families. * The Heteromitidae tend to be relatively rigid, and produce only temporary pseudopods. * The Cercomonadidae are more plastic, and when food supplies are plentiful may become amoeboid and even multinucleate. The classification of genera and species continues to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neocercomonas
''Neocercomonas'' is a protist genus of the order Cercomonadida. It consists of single-celled bacteriophagous organisms that usually live on or nearby terrestrial plants, both above and belowground. Species are biflagellate and may grow up to 60 micrometers long, with a trailing tail-like mass of protoplasm at their posterior end and a pair of roots connecting their posterior flagellum to the cytoskeleton. Etymology The genus was named by Ekelund ''et al.'' in 2004. The first three letters of the genus name are directly lifted from the Greek ''neo'', meaning 'new', whereas the second part refers to the closely related genus ''Cercomonas'', from which ''Neocercomonas'' was originally distinguished when the former was discovered not to be a monophyletic group. Hence, ''Neocercomonas'' can be interpreted as 'new ''Cercomonas. Higher classifications such as the phylum Cercozoa and the order Cercomonadida also bear similar names, though ''Cercomonas'' was identified first (in 1841). ...

Kraken (Cercozoa)
''Kraken'' is a genus of amoebae within the Cercozoa, containing the sole species ''Kraken carinae''. These amoebae are characterized by a small round cell body and a network of thin and very long filopodia that can reach up to a mm in diameter. Kraken amoebae feed on bacteria and live in freshwater and soil systems. Etymology ''Kraken'' was named after the German word Krakonen, which is the name used to refer to the Norse mythological monster. ''Kraken'' was named as such due to the method of feeding, in which the large network of branching filopodia grab bacteria and transports it to the cell body. The mythological monster Kraken was told to catch its prey with one of its many arms in a similar manner. History ''Kraken'' is a recently discovered genus, having first been described in 2016 at the University of Koln. Thomas Cavalier-Smith established the phylum Cercozoa in 1998, which consists of flagellates and filose amoebae that are widely morphologically diverse. Genetic a ...
